+<h3>Round 1 Instructions</h3>
+<hr>
+<p>
+This is the first round of the experiment. The length of the round is 4
+minutes. Like in the practice round you can collect green tokens. This time
+you earn <b>two cents</b> for each token collected. This time you
+<b>cannot</b> reset the distribution of green tokens. 
+</p>
+<p>
+In this round the renewable resource will become five times bigger.  You will share this
+larger environment with four other players in this room that have been randomly
+selected.  One group's resource environment is distinct from the other groups.
+</p>
+<p>
+Each of you has been assigned a number from 1 to 5.  These numbers will remain the
+same throughout the experiment but you will <b>not</b> be able to identify which
+person in the room has been assigned which number, so your anonymity is guaranteed.  
+
+The other four players will appear on the screen as blue dots 
+<img src="@CODEBASE_URL@/images/gem-other.gif"> with a white
+number embedded in the dot.  On the top right corner of the screen you can see 
+how many tokens each player has collected. On the top left corner of the screen you can see 
+a clock that displays the remaining time in the round.</p>
+<p>Since you can only see the resource within your vision you may neither see all 
+the other participants nor all the resource units. The figure below indicates the 
+vision range compared to the whole environment</p>

+<h3>Round 4 Instructions</h3>
+<hr>
+<p>
+Round 4 is the same as the previous two rounds with two exceptions.  
+</p>
+<p>
+Before the next round starts you can anonymously communicate by text messages
+for four minutes with the other participants in your group. You can use this
+opportunity to discuss the experiment and coordinate your actions to improve
+your earnings. You may not promise side-payments after the experiment is
+completed or make any threats. You are also not allowed to reveal your real
+identity. We are monitoring the chat traffic while you chat.
+</p>
+<p>
+During the next round you will have the option to reduce the earnings of another
+participant at a cost to your own earnings.
+</p>
+<ul>
+<li>If you press the numeric key 1-5 corresponding to another participant, you
+will reduce the number of tokens they have collected in this round by two
+tokens. This will also reduce your own token amount by one token. The decision
+whether or when to use this option is up to you. 
+<li>When you reduce the number of tokens of another participant, they will
+receive a message stating that you have reduced their tokens. Likewise, if
+another participant reduces your number of tokens, you will also receive a
+message. These messages will be displayed on the bottom of your screen.
+<li>If your tokens are being reduced or you are reducing another participant's
+tokens, you will receive some visual cues.  When your tokens are being reduced
+your yellow dot will turn red briefly with a blue background.  The participant
+currently reducing your tokens will turn purple with a white background.
+<li>You may reduce the earnings of other participants as long as there are
+tokens remaining on the screen and while both you and the other participant
+have a positive number of tokens collected during the round.  <b>Each time</b>
+you press the numeric key corresponding to another participant your token
+amount is reduced by <b>one</b>, and their token amount is reduced by
+<b>two</b>.  <b>Note:</b> You can only remove tokens from a participant that is
+visible to you.
+</ul>

+

+The length of this round is four minutes.

+<h3>Facilitator Instructions</h3>
+<p>
+Welcome to the facilitator interface.  This interface allows you to control
+the experiment.  You may only modify configuration parameters <b>before</b>
+you start the experiment by selecting the Configuration menu.  When all the
+participants are ready to begin the experiment, you can start the experiment
+by selecting Experiment -&gt; Start.  After a round has been completed you
+will be able to view the statistics for all of the participants.  You can
+begin the next round by selecting Round -&gt; Start.

+<h3>General Instructions</h3>
+<p>
+Welcome. You have already earned 5 dollars by showing up at this experiment. You can
+earn more, up to a maximum of 40 dollars, by participating in this experiment, which
+will take about an hour to an hour and a half. The amount of money you earn depends
+on your decisions as well as the decisions of other people in this room during the
+six rounds of the experiment. 
+</p>
+<p>
+You appear on the screen as a yellow dot <img src="@CODEBASE_URL@/images/gem-self.gif">. 
+You move by pressing the four arrow keys on your keyboard.  You can move up, down,
+left, or right.  You have to press a key for each and every move of your yellow dot.  
+In this experiment you can collect green diamond shaped tokens 
+<img src="@CODEBASE_URL@/images/gem-token.gif"> and earn two cents for each collected token.  
+To collect a token, move your yellow dot over a green token and press the <b>space
+bar</b>.  If you move over a token without pressing the <b>space bar</> you do NOT
+collect that token.
+</p>
+
+<p>
+The tokens that you collect have the potential to regenerate.  After you have
+collected a green token, a new token can re-appear on that empty cell.
+However, the rate at which new tokens will appear depends on the number of
+adjacent cells with tokens.  The more tokens in the eight cells around
+an empty cell, the faster a new token will appear on that empty cell.  In other
+words, <b>existing tokens can generate new tokens</b>.  To illustrate this, please
+see refer to Image 1 and Image 2.  The middle cell in Image 1 denoted with an X has
+a greater chance of regeneration than the middle cell in Image 2.  When all
+neighboring cells are empty, there is <b>no chance for regeneration</b>.
